THOMAS UTLEY, OF LIVERPOOL, ENGLAND.

SHIPS VENTILATOR.

SPECIFICATION forming part f Letters Patent No. 484,348, dated October11, 1892.

Application filed June '7, 1892. Serial No. 435,840. (No model.)

l To all whom t may concern:

Be it known that I, THOMAS UTLEY, engineer,a subject of the Queen ofGreat Britain, and a resident of Stonycroft, Liverpool, England, haveinvented certain new and useful Improvements in or relating to ShipsVentilators, of which the following is a specification, reference beinghad to the accompanying drawings.

This invention relates to ships ventilators, and more especially toventilators of the kind or class described in the specification of priorLetters Patent granted to me, No. 17,422, A. D. 1888.

One feature of my present invention relates to the construction of suchventilators so as to make them applicable for Ventilating both bunker orballast-tank and cabin. My said improved ventilator can, however, beused for the cabin only.

Another feature of my present invention relates to the provision of aclosing-down cover in the side of the ship for masking or closing theopening or entrance to the ventilator.

In the accompanying drawings, Figurel is a vertical section takenthrough my improved combined cabin and bunker or ballast-tankventilator, taken on the line 0c .'r, Fig. 2. Fig.

2 is a horizontal section o'n the line y y, Fig. 1. Fig. 3 is a partialfront elevation of the said ventilator. Fig. 4 is an elevation of aportion ofthe shi ps side, showing the opening or entrance to theventilator.

Like letters of reference indicate corresponding parts throughout thedrawings.l

A is the body of the ventilator.

B B are the air or valve chambers. I have shown a ventilator providedwith two sets of valves separated by a partition-wall C.

D D are the Ventilating-doors, which are hinged at D D and provided withordinary retaining-screw clamps D2D2Vfor securing the same in the closedposition.

E is a pipe or communication leading from the bunker or ballast-tank toone of the air or valve chambers B, whereby the apparatus is made toventilate the bunker or ballast-tank as well as the cabin. For shuttingott the lead E when desired-as, for instance, in case the vvalves getout of order-I provide a screwdown cap or cover F, which works on a boltF or is otherwise suitably arranged, so that it can V'be screwed downupon a seat F2, provided around the valve-opening, and so close thatpart of the ventilator. When used for Ventilating the bunker, thecorresponding door D is closed. Upon opening the said door D access isobtained to the cap or cover F for the purpose ot' raising and loweringthe same.

For masking or closing the opening or entrance to the ventilator, whendesired, I provide as follows-that is to say: G is a suitable open-metalframe, preferably made of brass or gun-metal to withstand shocks,secured in the ships side G. H is a water-tight cover or lid, which canbe fixed by bolts Hvto the interior of the said frame G, thereby maskingor closing the entrance to the ventilator and allowing of the ventilatorbeing shut ott in ease of accident to the valves or otherwise, or incase the side lights which are fixed in the opening A of the frame becarried away by heavy seas or otherwise damaged. Vhere it is desired toventilate the bunker or ballasttank only, I dispense with thedivision-wall C and provide a closing-down cap for both valves or allthe valves, if there are more than two sets.

What I claim is- 1. In a combined ships cabin and bunker or ballast-tankventilator, the combination, with a casing having an air or valvechamber, a valve mechanism, and a pipe or lead for connecting thevalve-chamber with a bunker or ballast-tank ventilator, of a seatarranged in juxtaposition to the valve-opening and a screw-down capadapted to move upon the seat for closing communication between the pipeor lead and the air or valve chamber, substantially as described.

2. In a combined ships cabin and bunker or ballast-tank ventilator, thecombination, with a casing having an air or valve chamber, aVentilating-door, and a pipe or lead for connecting the valve-chamberwith a bunker or ballast-tank, of a seat surrounding the valve-openingbetween the valve-chamber and the pipe or lead and a screw-down capadapted to close upon the seat for shutting oit communication betweenthe pipe or lead and the air or valve chamber, substantially asdescribed.
